  • Parkinson’s researchers focus on chemical from soil bacteria

    A chemical produced by common soil bacteria may kill neurons that produce dopamine, according to a study publishing Oct. 6. Dopamine neuron demise leads to the hallmark symptoms of Parkinson’s disease, a movement disorder affecting some 1 million Americans. The National Institutes of Health-sponsored research, publishing in the online open-access journal PLoS One, is preliminary, according to ...

  • Agricultural Bacteria: Blowing in the Wind

    It was all too evident during the Dust Bowl what a disastrous impact wind can have on dry, unprotected topsoil. Now a new study has uncovered a less obvious, but still troubling, effect of wind: Not only can it carry away soil particles, but also the beneficial microbes that help build soil, detoxify contaminants, and recycle nutrients. Using a powerful DNA sequencing technique, called ...

  • Common soil bacteria could clean up nuclear contamination

    Researchers are studying some common soil bacteria that “inhale” toxic metals and “exhale” them in a non-toxic form. The bacteria might one day be used to clean up toxic chemicals left over from nuclear weapons production decades ago. Using a unique combination of microscopes, researchers at Ohio State University and their colleagues were able to glimpse how the Shewanella oneidensis bacterium ...


  • Desert bacteria could help boost crop yields

    Desert soil microbes could help halt desertification and boost agriculture in arid regions of the Middle East and North Africa, according to a study.   Scientists from the United Arab Emirates [UAE] have isolated local salt- and drought-tolerant strains of Rhizobia, soil bacteria that fix nitrogen when they become established ...

  • Plants host pathogenic bacteria from livestock farming

    Disease-causing bacteria resulting from livestock farming can contaminate food products and find their way to humans. This occurs remarkably effectively via plants, which explains why recent outbreaks due to infection with EHEC and other E. coli and Salmonella strains are regularly attributed to the consumption of fresh vegetables. These are the findings of researchers from Wageningen UR ...

  • Keeping a pulse on the soil

    Leaving behind stubble is not ideal when shaving, but it’s a good practice to leave behind crop “stubble” after harvest. According to soil scientist Frank Larney, crop residue anchors the soil against wind and water erosion. Avoiding bare soils is one part of a soil conservation package he and his research team demonstrate in a 12-year experiment growing pulses in southern ...

  • Southern soils mitigate manure microbes

    That swine manure sprayed on to fields adds valuable nutrients to the soil is well known. But what is not known is whether all that manure is bringing harmful bacteria with it. A new study looks at the levels of nutrients and bacteria in soils of fields that have been sprayed with manure for fifteen years or more. The research team, composed of scientists from the USDA-ARS Crop Science Research ...

  • Antibiotic-eating bug unearthed in soil

    It’s well known how bacteria exposed to antibiotics for long periods will find ways to resist the drugs—by quickly pumping them out of their cells, for instance, or modifying the compounds so they’re no longer toxic. Now new research has uncovered another possible mechanism of antibiotic “resistance” in soil. In a paper publishing this week in the Journal of ...

  • Controlled ‘reset’ for nematode-infested soil

    Harmful nematodes that damage the soil can be controlled by creating an environment in which they are temporarily deprived of oxygen. Covering the soil with plastic film or a layer of water encourages anaerobic bacteria to produce fatty acids, which will kill most nematodes. “It does sometimes take a while,” says Leendert Molendijk, soil expert at Wageningen UR. Molendijk and his ...

  • Phosphorus-rich soils support larger invertebrates

    In a recent study, researchers have defined the relationship between soil conditions and nutrients with the health of soil ecosystems. The results suggest that organic grassland, rich in phosphorus, is supportive of large populations of bigger invertebrates. All living things are made up of chemical elements in certain proportions and the availability of these elements in the environment can ...

  • Soil organisms aid crop productivity by increasing yields

    Soil-living bacteria and fungi can be used to boost crop yields by more than 50 per cent without the use of fertilizers, an international research project has found. In combination with fertilizers, yields of key crops such as beans, can more than double, the scientists from seven countries discovered. The findings, the result of an international effort to unravel the mysteries of so-called ...

  • Through microbes, nitrogen alters soil carbon cycle

    Soil scientists studying bacterial communities in hardwood forests have found evidence that extra human-derived nitrogen deposited from the atmosphere can change the composition of the soil microbial community, with implications for carbon cycling and sequestration. Don Zak and Sarah Eisenlord from the University of Michigan conducted a study on the response the soil bacterial community to levels ...

  • Plant diversity: the secret to more nitrogen and carbon in soil

    Plants play a key role in soil carbon (C) and nitrogen (N) accumulation. New research suggests that plant diversity may have an important role to play in stimulating C and N storage in some soils. The findings suggest ways to improve carbon sequestration in grasslands and increase biomass production, for example for biofuel crops on nitrogen limited soils. Soil could be an important carbon sink ...

  • Soil biodiversity: functions, threats and tools for policy makers

    Human societies rely on the vast diversity of benefits provided by nature, such as food, fibres, construction materials, clean water, clean air and climate regulation. All the elements required for these ecosystem services depend on soil, and soil biodiversity is the driving force behind their regulation. With 2010 being the International Year of Biodiversity and with ...

  • Can Gardeners Catch Deadly Legionnaire’s Disease from Potting Soil?

    Most gardeners consider their hobby to be a healthy one, but they maybe unknowingly exposed to Legionnaire’s disease, a serious pneumonia that often has long term effects after the pneumonia has cleared.   Legionnaire’s disease can be caused by different species of Legionella bacteria Typically, the infection is caused by the inhalation of contaminated aerosolized water ...

  • Study by ARS microbiologist in Texas shows farming practices’ benefits to soil quality

    The first evaluation of alternative farming practices—based on changes in soil microbes—in the Texas High Plains has been done by an Agricultural Research Service (ARS) scientist. Soil microbiologist Veronica Acosta-Martinez has also done a similar analysis for land in USDA's Conservation Reserve Program (CRP), a first nationally. Changes in microbes can give a relatively early indication as to ...

  • Some but not all plants can defend themselves against disease on saline soil

    Some plants with resistance against a specific disease are also able to defend themselves effectively when they are stressed due to, for example, drought or saline soil. At the same time, the resistance of other plants no longer functions in these very same conditions. Although this had been assumed for some time, Wageningen scientist Christos Kissoudis is the first person to show why. As a ...

  • Secret to Healthy Soil, Black Worm Castings, Organic Fertilizers, Vermaplex

    Although it is not apparent, the soil in your garden or farm is living system teaming with life. The ‘soil food web’, is made up of millions of beneficial micro-organisms which supports the development, vigor and production of the plant. These organisms include, nematodes, fungi, protozoa, and bacteria, are also responsible for retaining water and nutrients and disease ...
